WebA semi-circle shaped rug has a diameter of 2 ft. What is the area of the rug? d = 2 ft; r = 1 ft; Area of circle = 3.14(1 ft (1 ft); Area of Circle = 3.14 ft 2; Area of semi-circle = 3.14 ft 2 ÷ 2; Area of semi-circle = 1.57 ft 2: 10: A spinner has 6 sectors, half of which are red and half of which are black. WebWe know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. x^2 + y^2 -4y = 21. Then complete the square for the y terms. x^2 + y^2 - 4y + 4 = 21 + 4.
